A nuts-and-bolts introduction to geographic information systems (GIS), this book outlines the basic concepts and diverse uses of this technology in a local government environment. Emphasizing the value of integrating data from various sources, the book provides a set of tools for improving the way public services are delivered, resources are managed, and policy decisions are made. Rather than stressing the computer technology that is so rapidly changing in the GIS industry, this book concentrates on the concepts upon which this technology is based: information systems design, computer-aided mapping, topological data structures, geographic base files, and land records systems. It also provides the latest information on the U.S. Census Bureau's TIGER files and the Global Positioning Satellite System established by the U.S. Department of Defense. Special features include fourteen case studies, a chapter describing the enormous effort required to set up and manage a typical GIS project, and an appendix on who is using GIS technology and how it is being used. Whether they run the GIS or help run the government, readers of An Introduction to Urban Geographic Information Systems will learn efficient and effective methods for improving the impact that local government has on its citizens.

This landmark book addresses the data conversion issues involved in geographic information systems (GIS) technology. Converting paper-based maps to digital files can be expensive, complicated, and time consuming. It is the first comprehensive handbook that cohesively integrates the many complex issues of data conversion into a single publication for the GIS professional as well as for the student or layperson. Written and edited by international authorities on GIS conversion, the handbook covers the subject from basic conversion issues and map digitizing to advanced data capture techniques.

This aims to make the computing principles underlying geographic databases understandable and accessible to current and potential users of such systems. It overviews database system philosophy; describes database concepts eg storage, retrieval, architecture, conceptual modeling, and database querying.It then focuses on the characteristics of GIS, spatial data and spatial databases, concluding with a discussion of current/future research trends.

The book addresses the problem of accuracy of spatial databases, and comprises of papers drawn from a wide range of physical and human systems, taking approaches which vary from statistical to descriptive. Together they present both a comprehensive review of existing knowledge, techniques and experience, and an analysis of critical research needs in this area of spatial data handling.

"The book is timely, packed with useful background information, and thought-provoking in its treatment of future prospects . . . the definitive guide to GIS." - Photogrammetric Engineering & Remote Sensing

The one-stop source for current and comprehensive information on GIS now in a new edition

The long-awaited Second Edition of Geographical Information Systems brings this definitive reference up-to-date with the latest developments in GIS techniques and practice. Completely restructured and rewritten by a select international team of almost 100 GIS experts, it remains the resource of choice for anyone seeking detailed, state-of-the-art information on all key aspects of this revolutionary spatial science technologyfrom underlying principles and methodology (Volume 1) to management and practical applications (Volume 2).

Unmatched in scope by any other reference on the subject, Geographical Information Systems, Second Edition provides crucial background on basic GIS concepts and addresses the radical shifts and changes that have taken place in GIS technology and its uses. The new edition comes complete with color illustrations, helpful cross-referencing, plus an extensive bibliography, a list of acronyms, and more a full range of features that make this landmark resource easier to use than ever.
